In short, need more details. Where are you planning to run this much power? Street/Track/Mix? How much tail wagging are you willing to accept? With as much as that turbo kit runs, FI, without install charges (unsure if you did the install yourself), why risk an accident on the street (if you are in fact trying to use all that power there)?

Hi, my FI was installed and tuned by Seb at SZ, it is very reliable and great. My goal is racing at street witch is 60-130mph some thing like that, I need better grip tire, I already have KWV3 and spl arms for suspension so all I need now is a new set of wheel and tire. what do you mean "getting any additional traction from any radial on an unprepped surface." ? the uneven road bump? I want no slip from 60mph, 3rd gear at 60mph if I can. You mean I should go play in drag race in track?

Do you have sport brakes in the rear or the base single piston rears ? You could run 17's with the bigger brakes and a Mickey or M&H (lower tire pressures on a warmish day should help you with traction). Or do one better and run 16's (don't know if 15's would clear) on the small base brakes and run a taller tire. Its all up to researching a decent setup for your purpose and power level !

Here, fixed it for you. Noop, I am not helping you hurt yourself or anyone else for that matter.
BTW, 650whp is slow and boring.
